I want to be able to watch movement from within and outside my home
I want to be able to install surveillance cameras to DVR and then to monitor
These are all very low end solutions

Here is a write-up that explains IP, analog and Hybrid CCTV systems and the pros and cons of each.
http://www.ascendentgroup.com/home.htm
Many people have a misconception that IP has Superior scalability then Analog but with the advancements of DVR's this simply isn't true, with our X3 DVR you can monitor up to 16,000 cameras using our Central management Suite each camera could even be from a different DVR and a different site.
What is the Advantage of IP?
Many of the so called advantages of IP simply don't hold water in the real world, IP is mainly Hype and marketing and outside of a few niche applications such as 1 camera installs, where MP cameras are needed or large scale wireless projects which represent about 2% of the total CCTV market, IP has very few advantages compared to analog based on performance, cost and reliability.
Analog transmits over the internet faster and uses less bandwidth this allows you view you cameras in real time and control PTZ cameras, IP has to much lag and latency to do either properly as it has to transmit and receive video over the network.
IP or Analog why choose ?
What Ascendent Technology has done is allowed our X4S standalone DVR's to work as IP servers to convert analog cameras into IP cameras ( 4/8/16ch) in a U1 or U2 rack mountable case. Its the best of both worlds a standalone DVR that works autonomously with storage, playback and searc, with the features of IP cameras to distribute video over networks and record on NVR's making a humongous CCTV system powered by Ascendent's Tri-fusion platform. ( Ascendents oes not charge for their 64CH NVR/Client software )
Scalability and flexibility
Ascendent's standalone, PC- DVR's and IP cameras can record at one resolution and stream at another, its integrated VBR and CBR lets you manage the amount of data and bandwidth that is used by each camera individually giving you the security and reliability of analog with the flexibility and interoperability IP to offer unlimited expandability by adding 1-64 cameras at a time. Ascendent's X4 Trifusion platform integrates the X4 PC, X4S standalone DVRs, X4-IP-Pro and, IP HD mega pixel cameras simultaneously. The Tri-fusion platform not only manages video but can integrate access control, analytics, biometrics, building management, NVR/DVRs, and other 3rd party applications from the leading security providers.
Cost Effective
The X4 Trifusion platform takes full advantage or prior security investments and existing wiring infrastructures while offering the best of breed technology creating a cost effective long term solution to suite the needs of small business to global enterprises.(unlike most companies Ascendent does not charge for their software you buy an IP product it will ship with our 64CH NVR server/client software)
IP cameras are usually based on CMOS
Analog cameras are based on CCD (usually)
CMOS has some significant disadvantages compared to CCD, this means CMOS
have inferior ability to cope with ambient lighting such as back light, bright, deep shadows contrasts, low light and IR this is also known as the real word.
File Size:
The smaller the files size the more images that are able to be sent and the faster they can be processed improving both FPS and speed. File size is the heart of any DVR and goes far beyond just its streaming capabilities as it also determines the recoding storage time, how much you can back up at once, how fast it renders and searches video. The file size of a DVR impacts the performance of the DVR in just about every aspect from speed to longevity and is often the most import spec of any DVR.
Most routers are not designed to handle IP cameras they have enough bandwidth but they are not able to process the amounts of commands. (9 IP cameras 30FP is 230 instructions per second) standard routers have enough bandwidth (up to 1GB) but cant handle the amount of tasks (instructions) so frames get dropped latency is introduced effectiveness of other devices such as POS, printers and data storage are affected and compromised.
IP does have applications and in some cases IP cameras are the only way to do a project but I would estimate that for 95% of applications analog is cheaper and higher performance with a lower cost of ownership and better reliability.
The best solution is using analog cameras with dvr's that have the ability to convert analog cameras into IP devices, that have on site storage so you only stream video over the network when you are viewing your cameras either LAN or WAN or to and from multiple sites.
